The Salmosa is an entry-level offering, yet features the same rubberised exterior as Razer's other high-end mice. The rear of the mouse starts in a raised position as per usual, however the descent down towards the front is a much steeper incline, with the buttons themselves being hinged quite far back — the result is a comfortable ambidextrous mouse where the tips of the fingers lie on the mouse buttons, rather than the whole mouse following the curve of your hand. The longer buttons also mean that regardless of hand size, you should be able to get some comfortable clicking action going on.
The scroll wheel/middle button as usual is centred between the two mouse buttons, is detented and offers good control. Unlike other Razer mice, the Razer logo does not glow on the Salmosa, instead it's a subtle silver colour.
The mouse uses infrared over the more modern laser technology, but the performance across multiple surfaces was good enough that you're highly unlikely to notice. On the underside of the mouse the sensitivity is switchable between 800dpi and 1,800dpi, while a second switch adjusts the USB polling rate between 125Hz, 500Hz and a crazy 1,000Hz (with the unfortunate side effect of disconnecting and reconnecting the mouse each time you change it), giving a large amount of flexibility. Having to flip the mouse over mid-game is definitely a disadvantage compared to those mice that feature easy to reach buttons on top of the device, but it's better to have the option there than not at all.
